resolve parent path for %q: %w

Error message

resolve parent path for %q: %w

What it means

filepath.EvalSymlinks failed on the file's parent directory while resolving symlinks to verify containment — typically the parent directory does not exist (file deleted after git status) or a permission/traversal error occurred. The relative path and OS error are wrapped for diagnosis.

Solutions

1. Check the wrapped error — usually the file or a parent directory does not exist (broken symlink or dangling path)
2. Recreate the missing parent directory or remove the broken symlink
3. Ensure the path resolves on the local filesystem before diffing it as a workspace change
